Title: Production of sintered body
Inventor: FUMEI FUMEI
IPC: B22F3/22
Filed: 1991-11-07
Abstract: PURPOSE:To efficiently produce a high-quality sintered body from a smooth high-density formed body by injecting a slurry into the cavity of an airtight forming die, packing a porous solvent absorbent in the injection port and then evacuating the die to remove the solvent. CONSTITUTION:A forming die 3 is formed from an airtight material such as silicone rubber capable of being cured at room temp. A slurry 6 of the forming material powder in solvent is injected into the cavity 4 of the die 3 from an injection port 5. The slurry 6 is obtained by dispersing about 80% of the forming material powder such as an Fe-Ni alloy powder having about 8mum particle diameter in a solvent consisting of an aq. about 1wt.% PVA soln. The injection port is filled with a porous solvent absorbent 7 of non-woven fabric, etc., and covered with a soft airtight sheet 9. The die is then evacuated from an exhaust pipe 10 through the absorbent 7 to remove the solvent. Consequently, a smooth and high-quality formed body is obtained in this way with good shape transferability. The formed body is detached from the die 3 and then heated, and a high-quality sintered body is obtained in a short time.

Title: Electric field effect transistor load circuit
Inventor: TANOI SATOSHI
IPC: H03H11/46
Filed: 1987-12-18
Abstract: PURPOSE:To cause a clamp current, which flows in the input side of the logic circuit of a next step, to be small, to cause energy consumption to be low and to improve the stability of operation by serially connecting a first FET (DFET) of a normally-on type, in which a gate and a source are connected, and a second DFET of the normally-on type, in which the gate is grounded, between a power source voltage and a node for driving circuit connection. CONSTITUTION:The voltage between gate and source of a DFET31 is constant at 0V and when a voltage between drain and source is small, the DFET31 goes to a non-satulating condition and it is operated as a resistance. When the voltage between drain and source is large, the DFET31 is satulated and it is operated as a constant current source. When a potential Va goes to be lowered, the conductance of a DFET32 goes to be large. When the potential Va goes to be larger than the conductance of the DFET31, the voltage of a load circuit 30 is pressure-divided into the both DFETs 31 and 32. Accordingly, since the DFET31 is satulated and goes to be the constant current source, a load characteristic can be obtained so that the conductance can go to be small rapidly.

Title: Erroneous transmission preventing method in facsimile
Inventor: YOSHIDA AKIHIRO
IPC: H04M1/57
Filed: 1990-11-27
Abstract: PURPOSE:To prevent the secrecy leakage oven if an erroneous connection occurs by comparing a telephone number sent from the other party side after a circuit is closed, with a telephone number of the other party destination stored at the time of transmission, and advancing a transmission procedure by its result. CONSTITUTION:A RAM 6 has an area for storing a telephone number of the other party at the time of dialing. At the time of transmission, an ID collating part 7 collates a telephone number sent from a receiving destination and the telephone number stored in the RAM 6 at the time of transmission, and outputs its result to a main control part 11. The main control part 11 decides it to be a correct connection only in the case both the telephone numbers coincide with each other and sends out facsimile information, and decides it to be an erroneous connection unless they coincide with each other and disconnects the circuit, and does not transmit a document. In such a way, even if an erroneous connection is executed to the other party which is not intended, it can be prevented that the contents of the document are sent out to the other party, and trouble caused by an erroneous connection can be reduced.

Abstract: PURPOSE:To drive a motor at an unerring rotational speed responding to a speed command, by providing a circuit for compensating a frequency error, which comprises a circuit for converting a frequency into a voltage and an integrating circuit, through adding it to a circuit for converting a voltage into a frequency. CONSTITUTION:An output pulse train P of a circuit 2 for converting a voltage into a frequency is inputted to a circuit 6 for converting a frequency into a voltage, and a voltage E2 proportional to the frequency of the output pulse train P is outputted. An error voltage E3 between a voltage E1 of a speed command 1 and the output voltage E2 of the circuit 6 for converting a frequency into a voltage, is inputted to an integrating circuit 5. The integrating circuit 5 outputs the resultant voltage of subtracting the error voltage E3 from a present voltage E4, to the circuit 2 for converting a voltage into a frequency. Thereby, the error, which is included in the output frequency of the circuit 2 for converting a voltage into a frequency owing to the change of its conversion characteristic, is compensated. Thereby, even when the characteristic of converting a voltage into a frequency, is changed, the pulse train P, whose frequency is always proportional to the voltage E1 of the speed command 1, is outputted from the circuit 2 for converting a voltage into a frequency.
